DISHWASHING MACHINE.

Application led January 7, 1920. Serial No.'349,982.

be suitable for use on dining cars and in other places where theavailable space is limited. The preferred construction by which Iaccomplish Such object is illustrated in the drawings and is hereinafterdescribed. lVhat I believe to be new is set forth in the claims.

In the drawings,-

Fig. 1 is a side view of my improved machine, some parts being insection and other parts being broken away in order better to show theconstruction;

Fig. 2`is a top view;

Fig. 3 is a vertical cross-section taken on line 3-3 of Fig. 1;

Fig. 4 is a vertical cross-section taken on line 4-4 of Fig. 1; and

Fig. 5 is a cross-sectional view taken substantially on line 5-5 of Fig.1.

Referring to the drawings,- indicates ai tank adapted to contain aquantity of wash water, the height of which may be ascertained through aglazed slght opening 11 1n one of the side walls of the tank, as shownin Fig. 4. 12 indicates a rinsing tank arranged over. a portion of thetank 10, leaving -a suflcient area thereof exposed for the introductionthereinto of baskets containing 'the dishes to be washed, as hereinafterdescribed. Both tanks are open at the top, and the bottom of the tank 12is preferably about midway between the top of the tank l() and thenormal level of the water therein, as shown in Fig. 1. A drain opensfrom the rinsing tank 12 into the lower portion of the tank 10 and isnormally closed by a valve 13 of any suitable type. Also an overflowpipe 14 leads from the upper part of the tank 12 and discharges into thetank 10.

Water is adapted to be supplied tothe tank 12 by means of a pipe 15 fromany suitable source and the tank 10,1nay, if desired, be

filled by overflow from the tank 12. It will be understood that asuitable cleansing agent is added to the water in the tank 10.

The water in both tanks is adapted to be heated by means of steam fromany suitable source admitted through a pipe 16 having nozzles 17, 18opening respectively into the tanks 12 and 10, as shown in Figs. 1 and2. The nozzles 17 and 18 are controlled by means of valves 19 and 2Orespectively.

The lower portion of the tank 10 between the level of the water thc reinand the bottom of the tank 12 is divided by a screen 21, the lowermargin of which extends into the water, as shown in Fig. 1. This screenpreferably is in alinement with the inner transverse wall cf the tank12, so that a washing compartm-.Jit 22 is provided which extends fromneai the' level of the water in the tank 10A up alongside of the tank 12and is open at the top for the reception of a suitable dish holdingbasket 23. `A screen 24 in the compartment 22 near the water levelsupports the basket during the washing operation.

At the opposite side of the screen 21 and vunder the tank 12 is a paddlewheel compartment 25 in which is mounted a paddle wheel 26 having blades27 arranged to take up Water from the tank 10 and throw it laterally anddownward through the screen 21 upon the articles in the compartment 22.A. delector 28 which extends over the out-er upper portion of saidpaddle wheel aids in properly directing the'water. It will be evidentthat as the tank 10 is quite deep and the dishes are near the bottom ofit while being washed, by thus directing the wash water downwards thereis practically nov danger of splashing water out of the tank.

The paddle wheel 26 is fixedly mounted upon ashaft 29 so as to rotatetherewith, and as best shown in Fig. 5, one end of said shaft extendsthrough an opening" in the wall of the tank 10, and is supported bymeans of an anti-friction bearing 30 of any `suitable type carried by asleeve b-racket 31 secured to the outside of the tank. A gasket 32 ofany suitable material is interposed between the shaft and the wall ofthe tank 10 for preventing water from splashing out .around the shaft,and a cap 33 is tightly fitted over the outer end of the sleeve bracket31 to prevent leakage and protect the bearing.

p Ast allationnin dining where'ljthe availab y '6.11 ther-more,.asf-most of the Water is'carried.

The other end ofthe shaft 29 is similarly mounted in an antifrictioribearing 34fitte'd in an external pocket in a housing-35 which is securedover the wall opening around 5 this end of the shaft. The shaft 29 isdriven by means of a bevel gear 39 keyed upon the outer end of saidshaft, which meshes with a bevel pinion 40 non-rotatably mounted uponthe lower end of a shaft 41 which has i a bearing in the housing 35. `Acap 42 closes the outer face ofthe housing 35, as best shown in Fig. 5.The upper. end of the shaft 41 is supported by a suitable bearingcarried by a bracket 43 which is secured to l the outside of the t-ankand comprises a hous- (ing 44 close-:l by a cap 45, as bestshown inFig. 1. vA bevel gear 46 is non`-rotatably mounted upon the upper end ofthe shaft 41, meshing with whichvis a bevel pinion 47 fixed upon thearmature shaft of a motor 48 which is mounted on top of the tank 10 atone side ofthe tank 12.' A hood 49 is preferably provided over themotor, which hood is removably secured at its edges tothe walls ofthetanks 10 and 12 in any suitthe screen 24 and the motor 48 is started.The Y paddle wheel is thereby rotated in a counterlclockwise directionas viewed in Fig. 1, so

Dthat the paddles 27 scoop up the water and dash it1 forcibly throughthe screen 21 upon the dishes in position on the support. By

reason of the paddle wheel being located be- ,low the tank 12, thebottom of said tank serves as a deflector and aids in directing thewater laterally into the washing compartment 22'. The mass of water'thrown by the paddle wheel is broken up to some extent by the screen 21so that it is well distributed over and among the dishes and they arethoroughly cleansed. When abasketful of 50 dishes has been washed thebasket is transferred to the rinsing tank 12 leaving the tank 10 free toreceive a fresh basket' for a 'repSetitionof the washin operation.

y the construction escribed I provide.

a very compacty and eicient machine by which dishes may be safely anduickly cleansed, and which is well adapted (ier incars and othersituations e space-is limited. Fur- `a ct i'c z .lly vat theiloor leveland both tanks jarepl," ed w ithi walls, there is prac-- fytfnoidanger`o` the splashing out of Water owin toswaying of the car, or theoperation o the machine. Both tanks and most of the operatiiig mechanismbeing enclosed by a continuous housing the machine presents a neatappearance, which is obviously desirable.

What I claim as my invention and desire to secure by Letters Patent, is-

1. )A washing machine comprising a housing containing a tank adaptedto/hold wash water, said housing being arranged for the l verticalintroduction into said tank or removal therefrom'of the dishes to bewashed, means for supporting dishes above the water in said tank, arinsing tank in saidehousing adjacent to said wash water tank, and meansin said housing below said rinsing tank adapted to throw Water from saidwash water tank toward the bottom ofthe rinsin tank and against thedishes carried by sai supporting means.

2. A washing machine comprising a tank adapted to containwash water,saidv tank being arranged for the vertical introducti'on thereinto orremoval therefrom of the dishes to be washed, a rinsing tank forming oneside wali of the upper ortion of sai wash water tank, and means elowsaid rinsing tank for throwing water laterally against dishes in thelower portion of said Wash water tankthe bottom of the rinsing tankforming a deflectcr which aids in ldirecting the wash water againstthedishes. 3. A washing machine comprising a housing containing a' tankadapted to hold wash water, said housing being arranged for thevvertical introduction into said tank or removal therefrom of the dishesto begwashed, means in said tank for supporting the ldishes above thewater therein, means at. one side of said tank for throwinwatertherefrom against the dishes carrie by said supportingmeans, arinsing tank 1n said ho'using above said water throwing means,the'bottom of said rinsing'tank being at a higher level than thatl ofthe wash Water in said wash water tank, and an Voverliow pipe lead-u ingfrom said rinsing tank to said wash water tank.

4. A washing machine comprising a housing 'containing a tank adapted tocontain tank, and means operativel connecting said said addle w eel."
